Adding a cookie not working on ios?

[SwannLV]

Environment

Flutter version: 1.17
Plugin version: 3.1.0
iOS version: 13.3
Device: Iphone11 simulator

Description

Adding a cookie is working for me on android but not on ios simulator.

Here is my code:

  final CookieManager _cookieManager = CookieManager.instance();

  @override
  void initState() {
    super.initState();

    final expiresDate =
        DateTime.now().add(Duration(days: 3)).millisecondsSinceEpoch;

    _cookieManager.deleteAllCookies();

    _cookieManager.setCookie(
      url: env.webAppUrl,
      name: "session",
      value: ClientProvider.token,
      domain: env.webAppCookieDomain,
      expiresDate: expiresDate,
      isSecure: true,
    );
  }

Have I missed some configuration?

Thanks a lot!

That's because you are deleteAllCookies and setCookie are async methods. You don't know which will be called first by the platform.
So, you need first call deleteAllCookies and then setCookie using await operator or then method on the deleteAllCookies result.

However, I noticed that expiresDate option is not working correctly on both iOS and Android platforms. I already fixed it and it will be available on the next release.

Here is an example using then method:

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';

Future main() async {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(new MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State<MyApp> {

  @override
  void initState() {
    super.initState();
  }

  @override
  void dispose() {
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        initialRoute: '/',
        routes: {
          '/': (context) => CookieManagerExample()
        }
    );
  }
}

class CookieManagerExample extends StatefulWidget {
  final CookieManagerExampleState state = CookieManagerExampleState();

  @override
  CookieManagerExampleState createState() => state;
}

class CookieManagerExampleState extends State<CookieManagerExample> {
  InAppWebViewController webViewController;
  final CookieManager _cookieManager = CookieManager.instance();

  @override
  void initState() {
    super.initState();

    final expiresDate =
        DateTime.now().add(Duration(days: 3)).millisecondsSinceEpoch;

    _cookieManager.deleteAllCookies().then((value) {
      _cookieManager.setCookie(
        url: "https://flutter.dev/",
        name: "session",
        value: "54th5hfdcfg34",
        domain: ".flutter.dev",
        expiresDate: expiresDate,
        isSecure: true,
      );
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        body: Container(
            child: Column(children: <Widget>[
              Expanded(
                child: Container(
                  child: InAppWebView(
                    initialUrl: "https://flutter.dev/",
                    initialHeaders: {},
                    initialOptions: InAppWebViewGroupOptions(
                        crossPlatform: InAppWebViewOptions(
                            debuggingEnabled: true
                        )
                    ),
                    onWebViewCreated: (InAppWebViewController controller) {
                      webViewController = controller;
                    },
                    onLoadStart: (InAppWebViewController controller, String url) {

                    },
                    onLoadStop: (InAppWebViewController controller, String url) async {
                      List<Cookie> cookies = await _cookieManager.getCookies(url: url);
                      cookies.forEach((cookie) {
                        print(cookie.name + " " + cookie.value);
                      });
                    },
                  ),
                ),
              ),
            ])
        )
    );
  }
}

@pichillilorenzo Any idea when this release will be up? I'm unable to set a cookie either in Android or iOS. I'm using await in an async function to first delete all cookies and then set them. When I run 'getCookie' immediately after, the cookie doesn't exist...

[jagged91]

    await _cookieManager.deleteAllCookies();
    await _cookieManager.setCookie(
        url:
            "url",
        name: "token",
        value: "value,
        domain: "domain",
        isSecure: true,
        expiresDate: anHourFromNow
        );

    var cookieData = await _cookieManager.getCookie(url:"url", name: "token");

Here's an example of what I'm doing, with some data redacted. When I print the list of cookies like you did in your example above, I don't see the cookie I just set. In addition, 'cookieData' is null.

@pichillilorenzo thanks a lot for your answer.
It does not seem to work on ios for me, chaining with a .then(..
Maybe it is because I am on the simulator?
Will try on a real device...

[pichillilorenzo]

@SwannLV I tested it on iOS simulator and it is working.

@SwannLV and @jgadsby could you try in a fresh app the example code I gave to you?
If the cookie for "https://flutter.dev/" url is set, then CookieManager is working. If it works with my example but not in your use case, then there is something else. In that case, I need more info about your use case (full code example that for you doesn't work), otherwise, I don't know what's going on and why it is not working for you.

[SwannLV]

I found my problem: cookie.domain not starting with a dot does seem to work on ios.
Thank you very much @pichillilorenzo for everything 🙏
